Park Tool HCW-9 Lock-ring & Cranks Wrench

This Park Tool headset wrench works great in the BMX industry as a lock-ring wrench.  The wrench is double sided with a 36mm and 40mm open end.  The 36mm side fits perfect for all Profile hub lock-rings while the 40mm side fits great on a number of other hubs that use aluminum lock-rings (Redline, Bombshell, Excess and other mini - expert hub sizes).

USE: Lock-ring installation/remover
